The attacker seems to be the admin of those two instances. Both instances have their registrations closed.
Edit: It is now open for both of them, or was already. I checked the Fediseer page for both instances and it still says that their registrations are closed.
Though it is suspicious that no captcha, email confirmation or manual approval is required for both of these instances. The admin of lemmy.doesnotexist.club seems to be inactive since their account creation yet this instance is still running. If the admin is the attacker, it could also be that they are the one behind the recent nicole spam.

Here is an example of the coordinated downvoting https://hackertalks.com/post/8692093
Of course its a controversial user who got someone angry enough to automated downvoting @DonaldJMusk@lemmy.today
But you can see every post they make gets 53ish downvotes from these two instances, plus some organic ones after a few hours.

A individual user airing their personal biases and manipulating lemmy isn’t good for the community, regardless of how you feel about their target. This is a really bad thing ™
Can your detection method be automated and federated?
I’m asking because this is probably the thin end of the wedge and is likely to increase exponentially, especially since anyone can set up an instance and do whatever they like with it.
I know one of these instances.
Fuck you, Nicole!
Seems relatively painless to chop those two instances off - chinese.lol has less than 200 users, and I can’t even find instance info for doesnotexist.club (coincidence? i think NOT).
I do personally wonder how difficult it is to spin up new instances though. How much effort would it be for them to create a new one and do it again?
I’m actually most concerned with the IP leaking of the fediverse chick posts - hopefully some progress has been made with the IP leaking in auto-loaded external media through DM’s
How much effort would it be for them to create a new one and do it again?
Minimal, but it is the domain that gets blocked so the attacker would still need to purchase a new domain.

I’m curious, what is it about IP leaking that concerns you? I’ve been thinking about it lately but I have a hard time seeing why it’s a problem.
Warned about this 11 days ago. https://lemmy.world/post/27449126
This is still a weakness of the current federation model imo
The attacker seems to be the admin of those two instances. Both instances have their registrations closed.
The alternative theory would be that these instances had open registrations, but rightly closed registration down after the admins noticed the bots. chinese.lol is on 0.18.4 with an admin with a 2 year old account, lemmy.doesnotexist.club has an admin with a 1 year account, and it was also that instance that the ‘nicole’ person has used before. This downvote attack would need to be a long time in the planning for what you’re suggesting to be true.
Upon inspecting the actual websites, the registrations seem to be actually open for both instances with no email confirmation, captcha or manual approval as one user pointed out. I checked the Fediseer page for these instances. What is the update delay for Fediseer?

I don’t know. It’s not something I’m familiar with - it might just default to saying ‘closed’ if it doesn’t have the data.
It’s interesting that the obvious bot accounts on those instances were set up in mid-March last year, so I’m guessing that these are somebody’s army that they’ve used before, but overplayed their hand when they turned it on the DonaldJMusk person. The admins can reasonably be blamed for setting up instances with open registrations and no protections and then forgetting about them, but I’d be wary of blaming them for being behind the attack directly. The ‘nicole’ person is unlikely to have used their own instance - it’s probably just someone with the same MO as whoever owns the bots, finding and exploiting vulnerable instances.

Nope. Fediseer displays unknown fields as N/A.

No, I don’t think they forgot. Would you forget about something you regularly pay for?
